#### Path Definition Tab - TTP Plane Circle Strategy

The Path Definition tab for the TTP Plane Circle strategy provides you with options to define a circular scan path. When the scan path is generated, the hit points are also selected based on the selection criteria that is currently specified on the Select Hits tab.

You can view the scan path whenever you update a path definition parameter and then move the cursor away. You can also view the updated scan path in the Graphic Display window.

Sample Path Definition tab

Rings

Type or select the number of rings.

First Diameter

Type the diameter of the first ring.

Offset

Type the distance between two rings.

Skip Rings

Type the ring number or numbers that you want to skip.

To skip rings 2 and 4, type 2,4. To skip rings 2 through 5, type 2-5.

Path Density

Type the number of points per mm that you want to use to create the scan path.

Start Angle

Type or select the start angle, in decimal degrees.

End Angle

Type or select the end angle, in decimal degrees.

Direction

Select CWS (clockwise) or CCW (counterclockwise).

Jump Hole

If you select this check box, it generates a break point in the scan path whenever the scan path is over the holes in the CAD surface. Type the required distance from the edge in the box.

If you select the Jump Hole check box, PC-DMIS looks for a break in the surface 360 degrees around every point in the path. If the path is closer than the jump hole distance from the edge, PC-DMIS jumps the path and then removes the path.
